Basic math calculation error/inconsistency with ACF

A multiplication of 81.10 x 100 = 8109.999999999999 in Lucee for some weird reason?
It correctly yields 8110 in ACF

Explanation of the general issue:

Lucee function that makes life easy:


I assume there has probably been a good amount of grumbling due to ACF non consistency on this but either way at least we have a resolution.

Thank again
